Immunotherapy in young adults with mature cystic ovarian Teratoma-Derived squamous cell carcinoma: a case series

Squamous cell carcinoma arising from MCTs is exceedingly rare in young adults and exhibits nonspecific clinical manifestations and imaging characteristics, hindering preoperative diagnosis. These tumors display highly aggressive biological behavior and are typically associated with a poor prognosis and a high postoperative recurrence rate. Immunotherapy intervention at diverse different time points for patients at different stages can increase their survival period.
